Efficient Arbitrary Simultaneously Entangling Gates on a trapped-ion quantum computer

Entanglement is a key ingredient in quantum computing. On a trapped ion quantum computer, parallel entangling operations have traditionally been implemented with the help of nonlinear solvers. In this talk, I will present an exact, linear protocol that entangles multiple arbitrary pairs of trapped-ion qubits. The protocol is efficient and can leverage the all-to-all connectivity available on trapped-ion quantum computers to implement up to quadratically many two-qubit gates at the same time.
